Twin Toughening‐Driven Martensitic Transformation Strategy Synergistic Improvement for Plasticity‐Thermal Shock Resistance of (Hf─Zr─Ti)C Ceramic Coating in Severe Thermal Environments

open access: yesAdvanced Science, EarlyView.
A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

From Ancient Techniques to Modern Solutions: In Situ Synthesis of C‐S‐H for Sandstone Conservation

open access: yesAdvanced Science, EarlyView.
Herein, this work presents a paleo‐inspired approach to synthesizing and optimizing C‐S‐H‐based grouting mortars for conserving the sandstone of Beishan Grottoes, Dazu Rock Carvings, China. By achieving an optimal recipe compatible with natural sandstone, this work demonstrates the pivotal role of hydrogen bonding in the adhesion between C‐S‐H mortars ...

Simple Protein Foaming‐Derived 3D Segregated MgO Networks in Epoxy Composites with Outstanding Thermal Conductivity Properties

open access: yesAdvanced Science, EarlyView.
MgO‐based composites with highly interconnected filler networks are fabricated using a simple, eco‐friendly protein foaming method. Liquid‐phase‐assisted sintering enhanced bonding with the matrix. The interconnected structured filler composites exhibit significantly improved thermal conductivity, exceeding that of pure epoxy, randomly dispersed ...
